Emotion research demonstrates that problems of theoretical interest or practical significance are not divided neatly along disciplinary boundaries. Researchers acknowledge both organic and social underpinnings of emotion, but the intersections between biological and structural processes can be difficult to negotiate. In this article, the authors…

In a series of 3 experiments modeled after infant studies, 3- to- 6-year-old children's intuitive knowledge about support was assessed. Different objects were shown either sufficiently supported or not. Children had to predict whether a block would remain standing on a platform upon release or make perceptual judgments about the possibility of a…

Two experiments were conducted to examine whether students use arguments with refutation in one text for evaluating the opposite arguments without refutation in another text. Undergraduate students read two conflicting texts in either of the two orders: pro arguments text first and con arguments text first. After reading each text, they evaluated…

Perceiving the orientation of objects is important for interacting with the world, yet little is known about the mental representation or processing of object orientation information. The tendency of humans and other species to confuse mirror images provides a potential clue. However, the appropriate characterization of this phenomenon is not…

This paper describes a very simple exercise using an inverted test tube pushed straight down into a column of water to determine the free-fall acceleration "g". The exercise employs the ideal gas law and only involves the measurement of the displacement of the bottom of the "diving bell" and the water level inside the tube with respect to the…

Previous research has shown that young children make a perseverative, gravity-oriented, error when asked to predict the final location of a ball dropped down an S-shaped opaque tube (Hood, 1995). We asked if providing children with verbal information concerning the role that the tubes play, in determining the ball's trajectory would improve their…

Dutch genomics research centers have developed the "DNA labs on the road" to bridge the gap between modern genomics research practice and secondary-school curriculum in the Netherlands. These mobile DNA labs offer upper-secondary students the opportunity to experience genomics research through experiments with laboratory equipment that…

The purpose of this series of experiments was to evaluate the effects of mixed mand-tact arrangements on the acquisition of mands and tacts in preschool-aged children. In Experiment 1, the effects of three training arrangements (mand-only training, tact-only training, and mand-tact training) were investigated with 3 typically developing children.…

The aim of this paper is to report on an experiment in the School of Management at the University of Surrey whereby the Scholarship of Teaching and Learning is being promoted through an approach which is organic in nature. The paper argues that the nature of such scholarship means that its promotion is more likely to be successful when the…

The temperature dependence of the dielectric permittivity is taken into account to study the energy change in a capacitor that follows a cycle between a cold and a hot thermal reservoir. There is a net energy gain in the process that, in principle, can be transformed into usable work. The paper is simple enough as to be used with keen…

This paper deals with temperature variations over time of objects placed in a constant-temperature environment in the presence of thermal radiation. After a historical introduction, the paper discusses cooling and warming laws, by taking into account first solely object-environment energy exchange by thermal radiation, and then adding…

The Gesture as Simulated Action (GSA) framework (Hostetter & Alibali, 2008) holds that representational gestures are produced when actions are simulated as part of thinking and speaking. Accordingly, speakers should gesture more when describing images with which they have specific physical experience than when describing images that are less…

Previous studies have demonstrated a dual-target cost in visual search. In the current study, the relationship between search for one and search for two targets was investigated to examine the effects of target prevalence and practice. Color-shape conjunction stimuli were used with response time, accuracy and signal detection measures. Performance…

On the basis of consistently finding significant overall costs to the ongoing task with a single salient target event, Smith, Hunt, McVay, and McConnell (2007) concluded that preparatory attentional processes are required for prospective remembering and that spontaneous retrieval does not occur. In this article, we argue that overall costs are not…

Einstein et al. (2005) predicted no cost to an ongoing task when a prospective memory task met certain criteria. Smith, Hunt, McVay, and McConnell (2007) used prospective memory tasks that met these criteria and found a cost to the ongoing task, contrary to Einstein et al.'s prediction. Einstein and McDaniel (2010) correctly noted that there are…
